Have Jerry Jones’ marketing efforts gone too far?

Primarily for marketing reasons, Jerry Jones had training camp in three cities in two time zones this summer.

Now comes the news Wednesday that the club is opening up four Saturday walkthrough practices at Cowboys Stadium this season to fans for prices ranging from $14.50 to $27.50.

Wade Phillips dismissed concerns that opposing teams could easily slip a spy into the crowd.

“If you can get anything out of that, let me know,” Phillips said. “You can look at the whole practice. Come on. They’re fixing to see something else in the game.”

OK, so it’s unlikely that opening the practices will result in opponents stealing team secrets. But here’s a bigger concern: Will the circus-like atmosphere at the walkthroughs diminish the players’ concentration level?

Considering all the mental mistakes that were made in the opener, the question has to be asked: Did all that travel during training camp and the preseason result in less attention to detail?

Jones is a marketing master who knows how to turn a buck, but all of his huckstering could be hurting the team.
